i'm having the same problem, trying to accomplish the following:
A VBox container has 2 children. State A shows both, state B shows only the
lower one, but it should fill the whole VBox.
Transition from state a to state b should move out the upper child and resize
the lower one, but when the animation starts, the upper child is removed
immediately. i've made a quick example:

Anyone knows how this transition could be accomplished ?
thanks!
